Accompanying drawing explanation
Figure 1 shows that the cross section structure schematic diagram of nuclear-magnetism room of the present utility model hemisphere monitor camera device;
Figure 2 shows that the A-A line cross-sectional view shown in Fig. 1.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As illustrated in fig. 1 and 2, nuclear-magnetism room of the present utility model hemisphere monitor camera device, comprise cuboid hollow and be provided with the aluminum alloy material shield shell 4 of fixing hole 6 at top, be fixedly connected with and the translucent cover 13 of the hemisphere plastic material arranged between two parties with the downside of described shield shell 4 by fixed mount 9, be arranged on the image-forming assembly 1 inside described translucent cover 13, and the power module be arranged on the bakelite fixed head 7 of described shield shell 4 inside and the monomode fiber transceiver 8 be connected with described image-forming assembly communication, described power module comprises the transformation assembly 10 be communicated with external power source, and to export with described transformation assembly and energy supply to the electromagnetic interface filter 5 of image-forming assembly and monomode fiber transceiver 8, wherein, voltage reduction module 12 is also provided with to adapt to its power reguirements between described monomode fiber transceiver and electromagnetic interface filter, described screening can is aluminum alloy material, described image-forming assembly comprises power zoom camera 1, lamp plate and circuit board and chip, the outside of described circuit board and chip and monomode fiber transceiver 8 and power module is enclosed with magnetic screen sheet, as foreign copper-nickel alloy sheet.Housing adopts aluminum alloy material and passes through grounding terminal block 11 fully ground connection, aluminium alloy conductance is very high, major part interference electromagnetic wave can be kept out or absorb to the Al alloy shell of abundant ground connection, simultaneously, the foreign copper-nickel alloy sheet of the skin band magnetic screen function of the circuit board of each module of housing and spherical shaped transparent cover inside and chip etc. is wrapped up, effectively can avoid the interference because each several part chip of excessively strong electromagnetic field to inside causes, ensure its stability in use.
Preferably, image-forming assembly of the present invention adopts the fully functional network video camera module of 200w pixel, can take the HD video of 1080p, and front lens adopts motorized zoom lens 1, can carry out the control zoom of 2.5mm-12mm.Camera lens and network modules adopt the direct plugging-in converting interface of 14 bayonet sockets to be fixed, the video analog signal collected by camera lens is become digital signal by network modules 2 and spreads out of, and zoom control signal passes to zoom lens by network modules, and then control to carry out Electronic control to zoom.Because the digital signal that the interference of strong magnetic field circumstance is exported by network modules can't directly spread out of, and will by its through monomode fiber transceiver be converted into light signal export gone out by optical cable transmission again.
Nuclear-magnetism room of the present utility model hemisphere monitor camera device adopts hemispheric transparent housing, is more convenient to the installation of product while adding the aesthetic property of product.And the intervention of web camera module makes camera network heighten degree, not only increase the imaging definition definition of video camera like this, other functional modules such as zoom, warning, recording can also be increased, be convenient to the expansion and upgrading functionally of product in the future.
Further, because camera and lamp plate are because imaging can be exposed in electromagnetic field environment, and be magnetized in order to avoid camera and affect its useful life, the medial surface of transparent plastic shell is covered with electromagnetic protection film 3 to strengthen the shielding to magnetic field, makes the continual and steady monitoring under strong magnetic field circumstance become possibility.
Again further, for improving the shield effectiveness to high-intensity magnetic field, be coated with copper silver conductive paint at the inner surface of described housing.Meanwhile, outside described shield shell, the strong permalloy layer of magnetic conductivity is also provided with to carry out passive magnetic screen.
The above is only preferred implementation of the present utility model; it should be noted that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
